Question

Work out the missing

Answer 1

The answer is 12

Use inverse operation

56 - 8 = 48

48 / 4 = 12

Then check if 12 is right

8 + 12 x 4 = 56

Answer 2

12

Explanation:

let the missing number be x

8 + x * 4 = 56

8 + 4x = 56

4x = 56 - 8

4x = 48

x = 48/4

x = 12

therefore missing number is 12
